VENTILATING ATTACHMENT FOR STOVES.

SPECIFICATION forming part of Letters Patent No. 354,765, dated December21, 1886.

Application filed June 22, 1886. Serial No. 205,925. (No model.)

T0 on whom it may concern:

Be it known that I, WARREN M. BRINKER- H OFF, a citizen of the UnitedStates, residing at Auburn,in the county of Cayuga and State of NewYork, have invented certain new and useful improvements in VentilatingAttachments for Stoves; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to a class of stoves known as ventilators, orventilatingstoves, and it consists in a new construction of theventilating air-pipes and of their connections. Heretofore such pipeshave been made Wholly separate and disconnected from. the stove andconnected to the smoke pipe or flue, or placed wholly within the stove,or placed wholly-within the stove'and made an integral part of the stovestructure. vWVhen such pipes are separate and placed at a distance fromthe stove, they take up an additional amount of room and are liable toinjury and displacement by contact with persons and articles moving pastthem, making frequent repairs necessary, and in the shipping of suchstoves the larger number of parts is a considerable objection.

In my improved construction the objections to an external pipe areavoided.

In the accompanying drawings,Figure 1 is a partial vertical section of arange or cookingstove, taken through the oven,with one form of myventilator-pipe attached thereto. Fig. 2 is a partial section of a stoveprovided with a short pipe-collar and an elbow detachably connectedthereto. Fig. 3 is a partial section of a similar but modifiedconstruction. Fig. 4 is a partial section of a stove with another formof outlet construction with my invention appliedthercto. Fig. 5 is apartial section of a similar construction, showing a connection with theoven, with dampers for controlling the air-inlets in theventilator-pipe. Fig. 6 is a view of a part of the rear of a stovehaving the construction shown in Fig. 5.

In the figures of the drawings, A designates the body of the stove,which may be of any-desired construction. The rear wall or top of suchstove is provided with means for attaching a smoke-pipe thereto.

b is the ventilating-pipe, which is shown in the stove.

the drawings as exterior to the stove, and lies adjacent to the wallthereof,below the point at which the smoke-pipe is attached, and isconnected with the body of the stove. The ventilating-pipe may beconstructed in any desired form.

In Fig. lthe ventilating-pipe 12 connects with a pipe, 0, within theelbow O, which is rigidly connected with the stove. The oven of thestove D is connected with the ventilating-passage b byanopening,d,forming an inlet to said pipe from the oven. Theventilating-passage is open at the side of the same, and has a dampercontrolling such opening. Theopening may be at the bottom of thepassage, instead of the side.

In Fig. 2 the pipe is shown as made separate from the stove, andattached to the rear Wall of the same by'bolts passing directly throughthe pipe and such wall. This pipe may be attached in any other suitableway.

In all the figures of the drawings I have shown the smoke-pipe connectedto the stove through the intervention of an elbow. This elbow issometimes detachable from the stove, and sometimes is rigidly connectedthereto.

It is, however, shown as being provided with an interior fine connectingwith and forming an extension of the ventilatingflue attached to thestove. These two parts of the ventilating-flue may be connected in anymanner.

In Fig. l the smoke-outlet of the stove consists of the elbow 0, rigidlyconnected with An opening is made through the lower wall of saidsmoke-outlet, close to the stove, and the pipe forming theventilatingpassage attached to the stove, is passed upthrough saidopening. A flue forming a con- 0 tinuation of the ventilating-passage isconnected to the said pipe by a loosely-fitting joint within said elbow.

In Figs. 2 and 3 I have shown two ways of uniting the parts'where thestove is provided with a collar, and the elbow is detachable therefrom,extending over the collar, as is usual. In Fig. 3 the elbow G isprovided with an air duct or flue extending along adjacent to the wallof the same, while the ventilating- 10o flue extends up through thecollar and has an extension backward, meeting the wall of the flue'orduct in the elbow, the end of the one overlapping the end of the other.This may obviously be changed and the ventilator'pipe extend only upjust through the collar, and the air flue or duct in the elbow beprovided with a hood. extending beyond the elbow to cover and connectwith the ventilating-pipe.

In Fig. 2 the ventilating-pipe is shown as extending up a short distanceabove the inner wall of the collar, and two separate pipes, c and 0",connected to it and extending centrally upward in the elbow, anddischarging in thesame or in the smoke-flue. This construction, it isobvious, can be used as well wherethe elbow takesa downward course fromthe collar of the stove. It is also obvious that these two parts, 0 and0, may be made in one piece, if desired.

In Fig. 4 I have shown another method of connecting theventilating-passage outside of the stove with the flue or pipe withinthe smoke-outlet. In this'eonstruction the range or stove is providedwith the elbow or its equivalent G, rigidly connected to the stove. Theventilating-pipe passes up into such elbow through the wall thereof, anda separate pipe is attached or connected thereto and extends upward anddischarges into the elbow near the upper end thereof, or into thesmoke-pipe. It is obvious that this pipe may be made to lie adjacent tothe outer wall of the elbow, as in other instances shown in thisapplication and in my former Patent No. 339,966; or the ventilating-pipemay extend upward through the elbow with little or no departure from adirect course and discharge near the top of the elbow or into thesmoke-pipe.

In Figs. 5and 6 I have shown my ventilating-flue connected with the ovenby a damper construction, 6. In this instance the lower end of theventilating-pipe is closed, as shown, and provided with an opening atone side which may be regulated or closed by a damper, e. It is to beunderstood that I may dispense with a damper in either of the air-inletsin this construction; or I may in all the. forms shown use a damper onthe ventilating-pipe, in order that the flow of air through the samemaybe regulated or entirely out off, as desired.

The connection of the ventilating-flue and the oven is of Value in thatit affords means for ventilating the oven, and it also assists increating a strong current through the ventilating-pipe. It may also befound desirable at times to close the direct opening in theventilating-pipe and remove the heated air from the oven. It willsometimes be found desirable to close both dampers until the walls ofthe smoke-outlet become heated. With even a damper in theVentilating-pipe alone the draft of air from the oven can be nicely adjusted.

I claim as my invention p 1. The combination, with a range or cookandopening therein, and communicating with the outer air, near the base ofthe stove, at or near its lower end, constituting an uninterruptedventilating-passage and an independent inlet from the oven to saidpassage, substantially as described.

3. The combination, with a stove, of a passage separate from the fluesof the stove communicating with the outer air, near the base of thestove, at or near its lower end, and extendingupward adjacent to andattached to the wall of the stove and communicating with thesmoke-outlet through the wall thereof, and discharging into the same,substantially as described.

4. The combination, with a range or cooking-stove, of a passageseparatefrom the fines of the range or stove, communicating with theouter air, near the base of the stove, at or near its lower end andextending upward adjacent to and outside of the walls of the stove,having communication through the wall of the smokeoutlet and discharginginto the same, forming an uninterrupted ventilating-passage and anindependent inlet from the oven to said passage, substantially asdescribed.

5. The combination, with a range or cooking-stove, of a passage separatefrom the flues of the stove having its upper and discharging end openinginto the smoke-outlet and communicating with the outer air, near thebase of the range or stove, at or near its lower end, forming anuninterrupted ventilating-passage and an independent inlet from the ovento said passage, and a damper controlling one of said inlets,substantially as described.

6. The combination, with a range or cooking-stove, of an elbow providedwith a duct or flue within the same and a ventilating-passage extendingupward adjacent to the wall of the stove and communicating with the fluewithin the elbow, said ventilating-flue communicating also with the ovenof the stove or range, substantially as described.

In testimony whereof I aiiix my signature in presence of two witnesses.
